计算两个日期之间的天数的正确方法是什么

import datetime

def calculate_days_between_dates(date1, date2):
    # 将日期转换为datetime对象
    dt1 = datetime.datetime.strptime(date1, "%Y-%m-%d")
    dt2 = datetime.datetime.strptime(date2, "%Y-%m-%d")
    
    # 计算时间戳之差
    timestamp_diff = (dt2 - dt1).total_seconds()
    
    # 将时间戳差转换为天数
    days = int(timestamp_diff / (24 * 60 * 60))
    
    return days

# 示例用法
date1 = "2022-01-01"
date2 = "2022-01-10"
days_between_dates = calculate_days_between_dates(date1, date2)
print("日期{}和日期{}之间的天数为{}".format(date1, date2, days_between_dates))
